- To all whom, it may concern:

Be it known that I, FRANCIS LEE STUART, a citizen of the United'States, residing in New York city, in the county and State of New York, have invented certain new and useful Improvements in Apparatus for Gonveying, Delivering, and Gathering Material, of which the following is a specification.

This. invention relates to apparatus for carrying material, broughtfrom a distance by a .ma inaconveyer belt, to a pile or place for storage or delivery, and also to apparatus for gathering material and depositmg it on a conveyer which'carries it to a distant point.

In my application for Patent No. 237 ,880, filed J une 3,1918, I have shown apparatus which so constructed that it may be operated to either deliver material main 'conveyer beltto a place for storage,

c or may gather material froma pile or source of supply. and deliver it"to said main conveyer belt." In such apparatus a tripper delivers to aconveyer belt carried by a boom mounted to .turnabout both vertical and horizontal axes. with means". for transferring material from the tripper to the boom conveyor, and it is also provided with a plow which gathers materialand transfers it to the boom conveyer which in turn delivers the material to the main conveyor belt. In said apparatus means is provided for operating the boom conveyer in opposite directions, 2'. e., in a direction to deliver material from its outer end or to receive material at its outer end and convey it inward and deliver it "to the main conveyor belt. I

According to my present invention instead of employing a plow on the outer end -of the boom convcyer and instead of operating the boom in opposite directions, I cmploy a grab bucket for gathering material and so mount it on the boom that without interference with said boom conveyer it may ather material from storage and deliver l li through'a suitable hopper to a main conveyor belt without employm the boom convqser for this purpose. In t is way the apparatus is adapted for use where a grab bucket i'smore suitable for gathering material than a plow.

My improvements are illustrated 111 the accompanyin drawings in which F gure l s ows a side elevation of the new apparatus.

from a Theboom is provided.

Fig. 2 is a plan view thereof..

Fig. 3 is a view similar to Fig. 1 but show ing the apparatus adjusted to deliver ma, terial from the boom conveyor to a hopper which transfers it to the mam conveyer belt.

Fig. 4 is a view-similar to Figs. 1 and :3, but illustrating modifiedv construction in which, instead of employing a movable hopper of the kind shown in Figs, 1, 2 and 3,

a stationary hopper is employed, z'.'e., .a hopper which is carried by the truck which supportsv the tripper and the boom conveyer.--

I A main conveyor belt A, as usual, is sup ported on rollers a, andmay be of any dosired length so as to convey material from a distant source of-supply. Itis provided with a looped portion or,tripper',A' suportcdon a frame'B, mounted on a truck the wheels 0 of which traverse a track D running parallel with the main conveyer belt. Said belt enters the apparatus at X, traverses the inclined portion 1) of the frame,

asses over a delivery roller 6, thence over Bend rollers 6 b and thence horizontally under the truck in the usual way. The de- I livery roller-discharges into a hopper E which is supported on and projects from the frame B of the-tripper. The hopp'er E delivers to another hopper F, supported by the frame of the delivery apparatus.

The truck G of the delivery apparatus is connected at g to the truck C and its wheels 9 traverse the track D. Motor mechanism H on the truck drives the wheels 9' and the truck supports a circular platform I on which is mounted a turntable K. The turntable revolves about vertical axis and may be operated by motor mechanism K; The boom supporting frame L is anchored to the turntable and the boom M is pivotally connected at onto the boom supporting frame so as to be able to turn about a horizontal axis. The boom-M carries an endless conveyer belt m of the usual kind.

For the purpose of raising and lowering the boom conveyor in order that it may de-- liver at any desired elevation, I provide a motor operated drum N which is connected with the boom by cables 0.

The apparatus thus far described is similar to that shown and claimed in my application forpatent filed may 31, 1919, No. 300,973, and is suitable for useas stacker or deliverer ofmaterial, but the same apparatus can be employed for gathering maveyer beltif equippet with a grab bucket T may be moved back conveyor to tl mounted on a truck mounted on wheels 4) traversing the track and. suitable operating mechanism.

In Fig. -1, Q illustrates a. grab bucket of n all known construction which may be suspended from the boom at g or it may be suspended at; g or at any other suitable point along the boom; The grab bucket'may be raised and lowered, and opened and closed by cables R extendlng to operating mcch'anlsm R of any suitable kind. T 1ndicates ahopper mounted on wheels t traversingthe track D. The hopper receives material at t and a belt tidclivers the material to a chute U, which in turn delivers it to the main conveyor belt A. The hopper and forth on the track to assume a suitable relation with the grab bucket. The boom conveyor may be raised and lowered'i'n the manner before described and swung about its vertical axis to any desired extent on either-side of the main conveyer belt and it may be operated to gather and raise material to a plane above the hopper T. The boom conveyer may then be moved to a. position over said hoppe -the grab bucketopened and material delivered.

In. Fig.

justed to deliver material-from the boom ratu's when delivering ordinarily piles the matcrial'on either side of the -mainjconveyer belt, it sometimes is desirable not to so deliver the material, but to pass it on to another point 01' indicated in Fig. 3. The hopper '1 may at any time be 'so adjusted as to come under the outer end of the boo|n-con\ 'eyer belt.

In Fig,

in which the hopper, instead of being veyer, is mounted on a truck movable coincidently with the truck of the boom convcyer. This hopper T is carricdby a truck D; The truck V is shown as being coupled at w to the truck (abut really forms a'con-' tinuatio n of this truck. In Fig; at the boom conveyor is shown in full lines 'as being adjusted to deliver-to the hopper T, the grab bucket at this time not being in operation, and it will be observed that the parts are so related with each other that they do notin any way interfere. The boom can be .adjusted to either deliver material to storage or to deliver to the hopper'as before explained. At this time the grab bucket will.

be drawn upout of operative position as indicated, or when it is'desn'ed to gather material from storageand transfer it to the boom conveyor 3 I have shown the apparatus ad--.

1e hopper. While the appato another apparatu which will deliver the material at some dlstaut point.- *This may be done in themannar' 4, have shown a modification- Inovable independently of thetruck which supports the boom con-- .belt and deliver-sit to storage,

main conveyor belt, the boom eonveyer may be turned and raised and lowered in any desired way, and when delivering to the hopper T it will, of course, be moved to a position over the hopper as indicated.

The -stacker shown in the accompanying drawings and hereinbefore described. is not herein claimed spccifically. Certain feailll't's of construction of said stacker are claimed in my application for Patent No. 300,973, tiled May 31, 1919.

I claim as my invention 1. Apparatus for reclaiming and convey iug material, comprising a main conveyor, a truck mounted to move parallel therewith, a boom conveyor supported at its inner end b v the truck to turn about a vertical axis,

means for delivering material from the a-hopper for delivering material to the main conveyor, a. grab bucket supported by the and delivering to said hopper, and means for operatlng the grab bucket.
